Vermont State Police released a surveillance video photograph depicting a suspect in an armed robbery that took place in Wallingford early Tuesday morning.

The unidentified man, who dressed all in black and covered his face with a mask, used a knife to threaten a clerk at the Smart Shop at 172 North Main St. The six-month pregnant woman is shown in the picture being led into a bathroom where her assailant left her while he robbed the store, according to police.

The man is described as being between 5-feet, 5-inches to 5-feet, 9-inches tall. No information about his age, race or other characteristics are known because the man covered himself completely with black clothing, gloves and a facemask.

Anyone with information about the incident is asked to call Detective Sgt. Albert Abdelnour at 773-9101.
